Abstract:
    We present observational results for extragalactic radio sources
    with milliarcsecond components, obtained with the 600 meter ring
    radio telescope RATAN-600 from 1st to 22nd December, 1997. For
    each source, a six frequency broad band radio spectrum was
    obtained by observing simultaneously with an accuracy up to a
    minute at 1.4, 2.7, 3.9, 7.7, 13 and 31 cm. The observed list is
    selected from Preston et al. (1985AJ.....90.1599P) VLBI survey and
    contains all the sources in the declinations between -30 and +43
    degrees with a correlated flux density exceeding 0.1 Jy at 13 cm. The
    sample includes the majority of sources to be studied in the current
    VSOP survey and the future RadioAstron Space VLBI mission.
